BMX’s new SolidSafe range promises slimmer, cooler-running magnetic power banks, with the 10K model offering the best balance of capacity and charging power.
BMX is attempting to bring a more advanced battery chemistry into a familiar accessory category with its SolidSafe range of magnetic power banks. The line uses semi-solid-state cells rather than conventional lithium-ion packs, a design BMX says contains far less liquid electrolyte and is intended to improve thermal stability while reducing the risk of swelling, overheating and fire. Android Central said this places the products among the first mainstream consumer power banks to use the approach, even if the technology is still an intermediate step rather than a fully solid-state battery. The range is available now through Amazon and starts at £59.99.
The most eye-catching model is the SolidSafe Air 5K. B&H Photo lists it as a 5,000mAh unit with 15W Qi2 magnetic wireless charging and up to 20W over USB-C, housed in a titanium enclosure. BMX claims a thickness of just 6.8mm, which helps explain why the Air is being positioned as a daily-carry option rather than a high-capacity travel battery. It is a slim, premium-feeling product, but that compactness comes with compromises: there is no colour screen, only basic LED indicators, and wired charging of the pack itself is limited to 15W.
The standard SolidSafe 5K follows the same 5,000mAh formula but trades some refinement for better day-to-day usability. According to BMX’s own product information, it is thicker than the Air at about 11.7mm, uses aluminium rather than titanium, and adds a full-colour display that shows battery percentage and charging wattage. It also includes a built-in USB-C cable that doubles as a lanyard, which is a practical touch for anyone who dislikes carrying extra leads. Wireless charging still tops out at 15W, while wired output reaches 20W.
For most people, though, the most balanced option may be the SolidSafe 10K. BMX says the larger model doubles capacity to 10,000mAh, lifts wired output to 30W and adds a second USB-C port, allowing up to three devices to charge at once alongside Qi2 wireless charging. The company also includes the same full-colour display and integrated USB-C lanyard cable. At 18.9mm thick and 230g, it is far less discreet than the Air, but it is better suited to long days away from a socket. Some commentators have noted that BMX’s semi-solid-state approach should be understood as an incremental safety improvement rather than a guarantee against battery faults, which makes the physical build quality and thermal management especially important. In that context, the 10K looks like the most sensible choice for travellers, while the Air remains the most striking model in the range.
